    Hello Mark, I have a stock 2001 F-250 PSD wt 7.3 and 130K miles.
    I understand you have a trans shop somewhere in Port St. Lucie and I live in Palm Beach County.
    I would like to have you install the row 6.0 tranny cooler in my truck as I have retired and will be towing a 10K fifth wheel out West this summer and would like a little extra insurance. I've maintained the truck impeccably since she was new. The trans is running great and has been flushed 2 or 3 times and as I am a very conservative driver, shift points have never altered. Smooth as glass.
    My phone number is 561-733-2614 and my name is Michael Galada.
    I hope you can/will assist me as I've followed your posts forever.

    Hey there Mark, I have a 2000 Ford Excursion with a 7.3 engine, around 15,000 miles ago I had my transmission replaced with a 4r100 transmission, recently it has been acting up and I have noticed a loss in power/response, the other day I was backing out to exit a parking lot and once I changed into drive I had to rev it up in order for it to engage, after putting 1 qt of ATF into it, it drove like it was brand new, i've noticed that the rear part that connects to the transfer case is pretty wet but it is still difficult to pinpoint the exact spot where the leak is coming from, if you could help me i'd very much appreciate it, you can reach me at my email [email protected], thank you!

    Thanks for your help on the transmission/TC issue! I posted some better pictures of the metal tabs if you get a chance to take a look

    Hello Mark

    You responded to my post last Oct about my son's '99 F250 4r100.

    We found the low frictions were completely worn. The "hub" of the forward drum cracked, allowing fluid to leak by the 2 sealing rings.

    I replaced the forward drum, all frictions, steels, sealing rings, new pump stator and gears. Installed "Tugger" kit and new TC .

    It didn't work. The truck it will not move in forward or reverse. Line pressure shows 20-30psi in neutral/park, 40-50psi in reverse or drive. Book says 17.7 qts of fluid, we put in 18.

    I used the ASTM book. Everything made sense and went together smoothly. Iv'e been a machinist for 35 yrs, and have rebuilt a few automatics already. Obviously I did something wrong this time.

    Can you think of anything I can check with the tranny still in the truck? At first I thought we got a bad new TC, but then found that it was low on pressure.

    Thank you for taking the time to read this, any help is greatly appreciated!

    Hi Mark-

    read alot of your posts, new to this board, on a few others & lurk here:

    1997 4WD F350 PS run hard acceleration in reverse with a big load & heard a bit of a rattle noise after let off the pedal that lasted for about 5 seconds. drove normal after but hour later hauling load up hills 15 miles later, temps went up fast to 240 and lost power at the transmission, dumping fluid from cover. shut it down, towed it home, drove off the truck, behaved like no fluid. dropped the trans, think front seal is leaking, fluid not burnt and fairly red, last change was at around 40k with temps 190 average & 220 occasional. ~100+hp over stock in mods. Plan to replace the seal and put it back on the truck. Any checks I should do while it is off? inspect the internals? TC looks good with no loose parts or other metal pieces in the case. Transmission was shifting great with no issue before and even up to power loss. previous owner claimed to have replaced/rebuilt transmission about 70k ago.

    Hello Mark,

    I had a quick question for you. I have an 03 F250 with a 5.4 that needs a tranny. That tranny should be a 4r100 correct? On last question I know of a parts truck but it is a 2000 with a v10 is that tranny also a 4r100? Thank you in advance!!

    Best Regards,
    Brandon

    Nobody has made MERCON since 2006. MERCON V replaced MERCON. Get over it.
